"I'm pretty sure Dilan thinks they're both the same species, as they walk at the same level and are both going through the stage of chewing on everything,” said Dilan's mother, Chicago photographer Ivette Ivens.

'It's honestly the most loving connection'

She brought Farley into the family after realizing that the pup shared the same birthday as her son: 26 May 2014. The two “instantly” developed a special connection. They do everything together, including sleeping, playing, eating and even bathing. "He patiently plays with him and tries not to snore while they both nap. It's honestly the most loving connection - pure, unconditional, irreplaceable and inseparable," Ivette told the Daily Mail. According to Ivette, as the two grow, so does their bond.

"[A]s Dilan grows bigger and understands more, he truly appreciates Farley's company and the love is just blossoming," she said. “My little Dilan is a chilled-out baby and he’s always happy, but for some reason Farley really cracks him up. I love seeing them together. “He cleans up Dilan’s mess after he eats, and always licks Dilan’s neck if he is crying, so he starts laughing out loud.”
